The Inception – Internet

intrnet beginningInternet today as we know was transformed into ARPANET. Very basic network switching was the technology involved in it which later moved to include packet satellite networks, ground-based packet radio networks and other networks. Idea behind using the Internet was connecting multiple independent networks of arbitrary design, beginning with the ARPANET  which follow a technical idea of open architecture networking.

Until that time, only one method of networking existing, which was the circuit switching method. This method, networks interconnects at the circuit level passes individual bits on a synchronous basis along a portion between a pair of end locations. What this means  is that in the circuit switching mode, there is a dedicated path by which data travels from the source to the destination. Packet switching mode, on the contarary has the hub or the router, which acts as the intermediary, decides the best path for sending or receiving the data packets thus increasing the data efficiency.

This skeleton worked as the base for future of networking. Further down the line, the TCP/IP (Transmission Control Protocol/Internet Protocol) was developed since the Network Control Protocol of NCP, which was in use at that time, did not have the ability to address networks. Thus the requirement for development of another protocol kindled the beginning of TCP/IP. Further, down-the-line Telnet and other basic application for remote logging and file transfer were developed. However, e-mail was the biggest innovation from that period. Other applications being developed at that time included packet-based voice communication (the precursor of Internet telephony), other models of file and disk sharing, also “worm” programs that showed the concept of viruses). Internet in this form was in it’s fledgling state, though, was very limited and soon the commercialisation of the Internet started looing a real avenue for innovators.
